Mitel 5000, VLAN, NetVanta and 5320 phones

[TechMB]

Could anyone help me with a setup for a Windows environment. The phone vendor that we have doesn't know how to setup the Windows side of the configuration nor the VLans for the switches and I found out after we purchased all the equipment.

Here's our configuration:
Router Sonicwall NSA 240 that has a 192.168.1.0/24 network on X0. I setup a sub-interface on the X0 as VLan10 on the 10.10.10.0/24 network.

Phone vendor sold us a NetVanta 1638p layer 3 switch. The switch has the default VLAN and up 192.168.1.2 address. There's also Vlan10 setup with address 10.10.10.2.  The ports on the switch are set to trunk. Also under each port there is an option to set the VLAN application so I selected voice VLAN 10 and it adds CoS 5 DSCP 46 automatically.  I'm having our Sonicwall do the routing for the networks so routing is not enabled on the switch. 

We have a 2008 R2 Windows server and followed the instructions from http://www.unixwiz.net/techtips/mitel-ipphone-networking.html to setup a scope on the 10.10.10.0 network for dhcp. The string I used was 
id:ipphone.mitel.com;sw_tftp=10.10.10.253;call_srv=10.10.10.253;vlan=10;l2p=6;dscp=56


The Mitel 5000 has the IP 10.10.10.253 address and on the switch it's setup on a non-trunk port VLan10

I'm able to ping from the 192.168.1.0 network to the 10.10.10.0 network. I can ping the Mitel 5000 with an IP of 192.x.x.x

I put a Mitel 5320 phone on one of the trunk ports and it boots up, displays VLAN 10 then it searches for an IP and displays using option 43:43 but never picks up an ip from the dhcp server.

Is there anything else I need to configure on the win08 server, the switch or the router for the phone to pick up an ip?

Router sounds like it's routing properly so no problem there.
There is no DHCP on VLAN 10. Phones sound like they are getting their VLAN info from the switch using voice vlan 10, this allow IP Phone devices to automatically configure themselves using CDP/LLDP.

I would just enable the DHCP server on the 5000 personally and it should work.

The problem you are having is that the 2008 server is not in VLAN 10 for obvious reasons. This means that no requests are coming through for phones as they have already put themselves in the voice vlan via the switch config.
If the switch supports dhcp helper(which it should) you set that on vlan 10 to direct requests to the 2008 server ip address which would in turn assign a lease based in the vlan 10 scope you set (10.10.10.0/24) and viola phones should boot.

Thanks I just needed to add the helper address and phones came up.
